PHP内爆阵列问题

新手技术难点在这里。希望我能解释清楚。我的数据库中有，我有snFreq，snFreq2，snFreqIV，snFreqTube，snFreqTrach，snFreqCath，snFreqWound和snFreqOstomy。我写了一个isset来检查每列是否存在数据，然后用预设文本创建一个变量。在所有的检查点之后，我想将它包含在一个短语中，但不想包含“0”数据。出于某种原因，我的输出仍然显示空白数据的多个逗号。下面是一个输出示例： SN频率/持续时间：QD X 60天+ 2次IV并发症，管状体并发症，，，< =有额外逗号的PRN访问？在我的DB中： snFreq = QD X 60 DAYS，snFreq2 = 1，snFreqIV =PHP内爆阵列问题

if(isset($rowPlanOfCare['snFreq'])){$snFreq = "SN FREQUENCY/DURATION: " . $rowPlanOfCare['snFreq'];} 
    if(isset($rowPlanOfCare['snFreq2'])){$snFreq2 = " + 2 PRN VISITS FOR ";} 
    if(isset($rowPlanOfCare['snFreqIV'])){$snFreqIV = "IV COMPLICATIONS";} 
    if(isset($rowPlanOfCare['snFreqTube'])){$snFreqTube = "TUBE FEEDING COMPLICATIONS";} 
    if(isset($rowPlanOfCare['snFreqTrach'])){$snFreqTrach = "TRACHEOSTOMY CARE COMPLICATIONS";} 
    if(isset($rowPlanOfCare['snFreqCath'])){$snFreqCath = "CATHETER CARE COMPLICATIONS";} 
    if(isset($rowPlanOfCare['snFreqWound'])){$snFreqWound = "WOUND CARE COMPLICATIONS";} 
    if(isset($rowPlanOfCare['snFreqOstomy'])){$snFreqOstomy = "OSTOMY CARE COMPLICATIONS";} 
    $snFrequency = $snFreq . $snFreq2 . implode(", ",array($snFreqIV, $snFreqTube, $snFreqTrach, $snFreqCath, $snFreqWound, $snFreqOstomy)) . "\n \n ";

最终输出应仅显示：SN频率/ DURATION：FOR IV并发症，管饲并发症< == QD X第60天+ 2 PRN VISITS没有其他逗号。

我希望你能帮我解决这个问题。提前致谢！ :)

isset是不一样的空（） – 2011-07-03 06:54:37

'如果（isset（$ rowPlanOfCare [ 'snFreqOstomy']）&& $ rowPlanOfCare [ 'snFreqOstomy'] =”“！）） – MLS

试试这个：

$snFrequency = $snFreq . $snFreq2 . implode(", ",array_filter(array($snFreqIV, $snFreqTube, $snFreqTrach, $snFreqCath, $snFreqWound, $snFreqOstomy))) . "\n \n ";
